Apple Maps also does not use tab bars because they don't have any other important screen in the app. In fact they don't even have any secondary screens so there is not much navigation UI.
The maps screen was their primary experience so they chose to hide everything under a single button. Now they have a lot of explore/discovery/updates features that they would like people to use - and hence the more prominent tab bar approach. https://twitter.com/sandofsky/status/1231348183218806784 …
Friends don't let friends dump anything and everything into the central Redux store. Store the bare minimum IDs, common state like user info and page/tab states. Use global caching for everything else. Use this to back your PR review comment: https://medium.com/@dan_abramov/you-might-not-need-redux-be46360cf367 …
